Abstract: This study aimed to
analyze: the level of profit and the gain difference of tomato’s lowland farming
between members and nonmembers of the farmer group and the factors of
production, production scale and efficiency of farm production of lowland
tomatoes in both members and nonmembers of farmer group. The number of respondents in this study was
taken by cencus method, in which all 62 farmer members and all 35 farmer
nonmembers were involved. The research
data was collected during October 2015 - January 2016 and was analyzed by R / C
ratios, different test (independent t-test), multiple linear regression using
the Cobb Douglas production function and NPM / Px ratio. The results showed that tomato farming was
profitable business and profitability of farmer group members was higher than
nonmembers’ farmers. Land and labor
significantly affected the production of tomatoes. Tomato farming of farmer group members
currently on the scale of production decreased (decreasing returns to scale)
and the nonmembers’ farmers that were in production scale fixed (constant return
to scale). The production process tomato
farming of both farmer group members and nonmembers farmer groups were not yet
efficient.
